RFC3949 - File Format for Internet Fax: This document is a revised version of RFC 2301. The revisions, summarized in the list attached as Annex B, are based on discussions and suggestions for improvements that have been made since RFC 2301 was issued in March 1998, and on the results of independent implementations and interoperability testing.; This RFC 2301 revision describes the Tag Image File Format (TIFF) representation of image data specified by the International Telecommunication Union (ITU-T) Recommendations for black-and-white and color facsimile. This file format specification is commonly known as TIFF for Fax eXtended (TIFF-FX). It formally defines minimal, extended, and lossless Joint Bi-level Image experts Group (JBIG) profiles (Profiles S, F, J) for black-and-white fax and base JPEG, lossless JBIG, and Mixed Raster Content profiles (Profiles C, L, M) for color and grayscale fax. These profiles correspond to the content of the applicable ITU-T Recommendations. [STANDARDS-TRACK]
RFC3950 - Tag Image File Format Fax eXtended (TIFF-FX) - image/tiff-fx MIME Sub-type Registration: This document describes the registration of the MIME sub-type image/tiff-fx. The encodings are defined by File Format for Internet Fax and its extensions. [STANDARDS-TRACK]
RFC3965 - A Simple Mode of Facsimile Using Internet Mail: This specification provides for "simple mode" carriage of facsimile data using Internet mail. Extensions to this document will follow. The current specification employs standard protocols and file formats such as TCP/IP, Internet mail protocols, Multipurpose Internet Mail Extensions (MIME), and Tagged Image File Format (TIFF) for Facsimile. It can send images not only to other Internet-aware facsimile devices but also to Internet-native systems, such as PCs with common email readers which can handle MIME mail and TIFF for Facsimile data. The specification facilitates communication among existing facsimile devices, Internet mail agents, and the gateways which connect them.; This document is a revision of RFC 2305. There have been no technical changes. [STANDARDS-TRACK]
RFC4141 - SMTP and MIME Extensions for Content Conversion: A message originator sometimes sends content in a form the recipient cannot process or would prefer not to process a form of lower quality than is preferred. Such content needs to be converted to an acceptable form, with the same information or constrained information (e.g., changing from color to black and white). In a store-and-forward environment, it may be convenient to have this conversion performed by an intermediary. This specification integrates two ESMTP extensions and three MIME content header fields, which defines a cooperative service that permits authorized, accountable content form conversion by intermediaries. [STANDARDS-TRACK]
RFC4142 - Full-mode Fax Profile for Internet Mail (FFPIM): Classic facsimile document exchange represents both a set of technical specifications and a class of service. Previous work has replicated some of that service class as a profile within Internet mail. The current specification defines "full mode" carriage of facsimile data over the Internet, building upon that previous work and adding the remaining functionality necessary for achieving reliability and capability negotiation for Internet mail, on a par with classic T.30 facsimile. These additional features are designed to provide the highest level of interoperability with the standards-compliant email infrastructure and mail user agents, while providing a level of service that approximates what is currently enjoyed by fax users. [PROPOSED STANDARD]
RFC4143 - Facsimile Using Internet Mail (IFAX) Service of ENUM: This document describes the functional specification and definition of the ENUM Naming Authority Pointer (NAPTR) record for IFax service. IFax is "facsimile using Internet mail". For this use, the Domain Name System (DNS) returns the email address of the referenced IFax system. This mechanism allows email-based fax communication to use telephone numbers instead of requiring the sender to already know the recipient email address. [STANDARDS-TRACK]
RFC4160 - Internet Fax Gateway Requirements: To allow connectivity between the General Switched Telephone Network facsimile service (GSTN fax) and the e-mail-based Internet Fax service (i-fax) an "Internet Fax Gateway" is required. This document provides recommendations for the functionality of Internet Fax Gateways. In this context, an "offramp gateway" provides facsimile data transmission from i-fax to GSTN fax; vice versa, an "onramp gateway" provides data transmission form GSTN fax to i-fax. The recommendations in this document apply to the integrated service including Internet Fax terminals, computers with i-fax software on the Internet, and GSTN Fax terminals on the GSTN. This memo provides information for the Internet community.
RFC4161 - Guidelines for Optional Services for Internet Fax Gateways: To allow connectivity between the general switched telephone network facsimile service (GSTN fax) and the e-mail-based Internet Fax service (i-fax), an "Internet Fax Gateway" is required. This document provides guidelines for the optional functionality of Internet Fax Gateways. In this context, an "offramp gateway" provides facsimile data transmission from i-fax to GSTN fax; vice versa, an "onramp gateway" provides data transmission from GSTN fax to i-fax. The recommendations in this document apply to the integrated service including Internet Fax terminals, computers with i-fax software on the Internet, and GSTN fax terminals on the GSTN.; This document supplements the recommendation for minimal features of an Internet Fax Gateway. In particular, it covers techniques for dropping duplicated fax messages, automatic fax re-transmission, error, return notice, and log handling, and possible authorization methods by DTMF (Dual Tone Multi-Frequency) for onramp gateways. This memo provides information for the Internet community.
